It currently supports the full Merkle-Patricia Trie and has all Shanghai opcodes implemented. - -## Performance - -This implementation is able to provide transaction level proofs which are then recursively aggregated into a block proof. This means that proofs for a block can be efficiently distributed across a cluster of computers. As these proofs use Plonky2 they are CPU and Memory bound. The ability to scale horizontally across transactions increases the total performance of the system dramatically. End-to-end workflows are currently in progress to support this proving mode against live evm networks. - -Furthermore the implementation itself is highly optimized to provide fast proving times on generally available cloud instances and does not require GPUs or special hardware. - -## Ethereum Compatibility - -The aim of this module is to initially provide full ethereum compatibility. Today, all [EVM tests](https://github.com/0xPolygonZero/evm-tests) for the Shanghai hardfork are implemented.

All design choices were made -to make sure these properties can be adequately translated into constraints of degree at most 3 while minimizing the size of the different -table traces (number of columns and number of rows). - -In this section, we will detail some of these choices. - -\subsection{Kernel} -The kernel is in charge of the proving logic. This section aims at providing a high level overview of this logic. For details about any specific part of the logic, one can consult the various ``asm'' files in the \href{https://github.com/0xPolygonZero/plonky2/tree/main/evm/src/cpu/kernel}{``kernel'' folder}. - -We prove one transaction at a time. These proofs can later be aggregated recursively to prove a block. Proof aggregation is however not in the scope of this section. Here, we assume that we have an initial state of the EVM, and we wish to prove that a single transaction was correctly executed, leading to a correct update of the state. - -Since we process one transaction at a time, a few intermediary values need to be provided by the prover. Indeed, to prove that the registers in the EVM state are correctly updated, we need to have access to their initial values. When aggregating proofs, we can also constrain those values to match from one transaction to the next. Let us consider the example of the transaction number. Let $n$ be the number of transactions executed so far in the current block. If the current proof is not a dummy one (we are indeed executing a transaction), then the transaction number should be updated: $n := n+1$. Otherwise, the number remains unchanged. We can easily constrain this update. When aggregating the previous transaction proof ($lhs$) with the current one ($rhs$), we also need to check that the output transaction number of $lhs$ is the same as the input transaction number of $rhs$. - -Those prover provided values are stored in memory prior to entering the kernel, and are used in the kernel to assert correct updates. The list of prover provided values necessary to the kernel is the following: -\begin{enumerate} - \item the previous transaction number: $t_n$, - \item the gas used before executing the current transaction: $g\_u_0$, - \item the gas used after executing the current transaction: $g\_u_1$, - \item the state, transaction and receipts MPTs before executing the current transaction: $\texttt{tries}_0$, - \item the hash of all MPTs before executing the current transaction: $\texttt{digests}_0$, - \item the hash of all MPTs after executing the current transaction: $\texttt{digests}_1$, - \item the RLP encoding of the transaction. -\end{enumerate} - -\paragraph*{Initialization:} The first step consists in initializing: -\begin{itemize} - \item The shift table: it maps the number of bit shifts $s$ with its shifted value $1 << s$. Note that $0 \leq s \leq 255$. - \item The initial MPTs: the initial state, transaction and receipt tries $\texttt{tries}_0$ are loaded from memory and hashed. The hashes are then compared to $\texttt{digests}\_0$. - \item We load the transaction number $t\_n$ and the current gas used $g\_u_0$ from memory. -\end{itemize} - -If no transaction is provided, we can halt after this initialization. Otherwise, we start processing the transaction. The transaction is provided as its RLP encoding. We can deduce the various transaction fields (such as its type or the transfer value) from its encoding. Based on this, the kernel updates the state trie by executing the transaction. Processing the transaction also includes updating the transactions MPT with the transaction at hand. - -The processing of the transaction returns a boolean ``success'' that indicates whether the transaction was executed successfully, along with the leftover gas. - -The following step is then to update the receipts MPT. Here, we update the transaction's bloom filter. We store ``success'', the leftover gas, the transaction bloom filter and the logs in memory. We also store some additional information that facilitates the RLP encoding of the receipts later. - -If there are any withdrawals, they are performed at this stage. - -Finally, once the three MPTs have been updated, we need to carry out final checks: -\begin{itemize} - \item the gas used after the execution is equal to $g\_u_1$, - \item the new transaction number is $n+1$ if there was a transaction, - \item the three MPTs are hashed and checked against $\texttt{digests}_1$. -\end{itemize} -Once those final checks are performed, the program halts. - -\subsection{Simple opcodes VS Syscalls} -For simplicity and efficiency, EVM opcodes are categorized into two groups: ``simple opcodes'' and ``syscalls''. Simple opcodes are generated directly in Rust, in \href{https://github.com/0xPolygonZero/plonky2/blob/main/evm/src/witness/operation.rs}{operation.rs}. Every call to a simple opcode adds exactly one row to the \href{https://github.com/0xPolygonZero/plonky2/blob/main/evm/spec/tables/cpu.tex}{cpu table}. Syscalls are more complex structures written with simple opcodes, in the kernel. - -Whenever we encounter a syscall, we switch to kernel mode and execute its associated code. At the end of each syscall, we run EXIT\_KERNEL, which resets the kernel mode to its state right before the syscall. It also sets the PC to point to the opcode right after the syscall. - -Exceptions are handled differently for simple opcodes and syscalls. When necessary, simple opcodes throw an exception (see \ref{exceptions}). This activates the ``exception flag'' in the CPU and runs the exception operations. On the other hand, syscalls handle exceptions in the kernel directly. - -\subsection{Privileged instructions} - -To ease and speed-up proving time, the zkEVM supports custom, privileged instructions that can only be executed by the kernel. -Any appearance of those privileged instructions in a contract bytecode for instance would result in an unprovable state. - -In what follows, we denote by $p_{BN}$ the characteristic of the BN254 curve base field, curve for which Ethereum supports the -ecAdd, ecMul and ecPairing precompiles. - -\begin{enumerate}[align=left] - \item[0x0C.] \texttt{ADDFP254}. Pops 2 elements from the stack interpreted as BN254 base field elements, and pushes their addition modulo $p_{BN}$ onto the stack. - - \item[0x0D.] \texttt{MULFP254}. Pops 2 elements from the stack interpreted as BN254 base field elements, and pushes their product modulo $p_{BN}$ onto the stack. - - \item[0x0E.] \texttt{SUBFP254}. Pops 2 elements from the stack interpreted as BN254 base field elements, and pushes their difference modulo $p_{BN}$ onto the stack. - This instruction behaves similarly to the SUB (0x03) opcode, in that we subtract the second element of the stack from the initial (top) one. - - \item[0x0F.] \texttt{SUBMOD}. Pops 3 elements from the stack, and pushes the modular difference of the first two elements of the stack by the third one. - It is similar to the SUB instruction, with an extra pop for the custom modulus. - - \item[0x21.] \texttt{KECCAK\_GENERAL}. Pops 2 elements (a Memory address, followed by a length $\ell$) and pushes the hash of the memory portion starting at the - constructed address and of length $\ell$. It is similar to KECCAK256 (0x20) instruction, but can be applied to any memory section (i.e. even privileged ones). - - \item[0x49.] \texttt{PROVER\_INPUT}. Pushes a single prover input onto the stack. - - \item[0xC0-0xDF.] \texttt{MSTORE\_32BYTES}. Pops 2 elements from the stack (a Memory address, and then a value), and pushes - a new address' onto the stack. The value is being decomposed into bytes and written to memory, starting from the fetched address. The new address being pushed is computed as the - initial address + the length of the byte sequence being written to memory. Note that similarly to PUSH (0x60-0x7F) instructions, there are 32 MSTORE\_32BYTES instructions, each - corresponding to a target byte length (length 0 is ignored, for the same reasons as MLOAD\_32BYTES, see below). Writing to memory an integer fitting in $n$ bytes with a length $\ell < n$ will - result in the integer being truncated. On the other hand, specifying a length $\ell$ greater than the byte size of the value being written will result in padding with zeroes. This - process is heavily used when resetting memory sections (by calling MSTORE\_32BYTES\_32 with the value 0). - - \item[0xF6.] \texttt{GET\_CONTEXT}. Pushes the current context onto the stack. The kernel always has context 0. - - \item[0xF7.] \texttt{SET\_CONTEXT}. Pops the top element of the stack and updates the current context to this value. It is usually used when calling another contract or precompile, - to distinguish the caller from the callee. - - \item[0xF8.] \texttt{MLOAD\_32BYTES}. Pops 2 elements from the stack (a Memory address, and then a length $\ell$), and pushes - a value onto the stack. The pushed value corresponds to the U256 integer read from the big-endian sequence of length $\ell$ from the memory address being fetched. Note that an - empty length is not valid, nor is a length greater than 32 (as a U256 consists in at most 32 bytes). Missing these conditions will result in an unverifiable proof. - - \item[0xF9.] \texttt{EXIT\_KERNEL}. Pops 1 element from the stack. This instruction is used at the end of a syscall, before proceeding to the rest of the execution logic. - The popped element, \textit{kexit\_info}, contains several pieces of information like the current program counter, the current amount of gas used, and whether we are in kernel (i.e. privileged) mode or not. - - \item[0xFB.] \texttt{MLOAD\_GENERAL}. Pops 1 elements (a Memory address), and pushes the value stored at this memory - address onto the stack. It can read any memory location, general (similarly to MLOAD (0x51) instruction) or privileged. - - \item[0xFC.] \texttt{MSTORE\_GENERAL}. Pops 2 elements (a value and a Memory address), and writes the popped value from - the stack at the fetched address. It can write to any memory location, general (similarly to MSTORE (0x52) / MSTORE8 (0x53) instructions) or privileged. -\end{enumerate} - - -\subsection{Memory addresses} -\label{memoryaddresses} - -Kernel operations deal with memory addresses as single U256 elements. -However, when processing the operations to generate the proof witness, the CPU will decompose these into three components: - -\begin{itemize} - \item[context.] The context of the memory address. The Kernel context is special, and has value 0. - - \item[segment.] The segment of the memory address, corresponding to a specific section given a context (eg. MPT data, global metadata, etc.). - - \item[virtual.] The offset of the memory address, within a segment given a context. -\end{itemize} - -To easily retrieve these components, we scale them so that they can represent a memory address as: - -$$ \mathrm{addr} = 2^{64} \cdot \mathrm{context} + 2^{32} \cdot \mathrm{segment} + \mathrm{offset}$$ - -This allows to easily retrieve each component individually once a Memory address has been decomposed into 32-bit limbs. - - -\subsection{Stack handling} -\label{stackhandling} - -\subsubsection{Top of the stack} - -The majority of memory operations involve the stack. The stack is a segment in memory, and stack operations (popping or pushing) use the memory channels. -Every CPU instruction performs between 0 and 3 pops, and may push at most once. However, for efficiency purposes, we hold the top of the stack in -the first memory channel \texttt{current\_row.mem\_channels[0]}, only writing it in memory if necessary. - -\paragraph*{Motivation:} - -See \href{https://github.com/0xPolygonZero/plonky2/issues/1149}{this issue}. - -\paragraph*{Top reading and writing:} - -When a CPU instruction modifies the stack, it must update the top of the stack accordingly. There are three cases. - -\begin{itemize} - \item \textbf{The instruction pops and pushes:} The new top of the stack is stored in \texttt{next\_row.mem\_channels[0]}; it may be computed by the instruction, -or it could be read from memory. In either case, the instruction is responsible for setting \texttt{next\_row.mem\_channels[0]}'s flags and address columns correctly. -After use, the previous top of the stack is discarded and doesn't need to be written in memory. - \item \textbf{The instruction pushes, but doesn't pop:} The new top of the stack is stored in \texttt{next\_row.mem\_channels[0]}; it may be computed by the instruction, -or it could be read from memory. In either case, the instruction is responsible for setting \texttt{next\_row.mem\_channels[0]}'s flags and address columns correctly. -If the stack wasn't empty (\texttt{current\_row.stack\_len > 0}), the instruction performs a memory read in \texttt{current\_row.partial\_ channel}. \texttt{current\_row.partial\_channel} -shares its values with \texttt{current\_ row.mem\_channels[0]} (which holds the current top of the stack). If the stack was empty, \texttt{current\_row.partial\_channel} -is disabled. - \item \textbf{The instruction pops, but doesn't push:} After use, the current top of the stack is discarded and doesn't need to be written in memory. -If the stack isn't empty now (\texttt{current\_row.stack\_len > num\_pops}), the new top of the stack is set in \texttt{next\_row.mem\_channels[0]} -with a memory read from the stack segment. If the stack is now empty, \texttt{next\_row.mem\_channels[0]} is disabled. -\end{itemize} - -In the last two cases, there is an edge case if \texttt{current\_row.stack\_len} is equal to a \texttt{special\_len}. For a strictly pushing instruction, -this happens if the stack is empty, and \texttt{special\_len = 0}. For a strictly popping instruction, this happens if the next stack is empty, i.e. if -all remaining elements are popped, and \texttt{special\_len = num\_pops}. Note that we do not need to check for values below \texttt{num\_pops}, since this -would be a stack underflow exception which is handled separately. -The edge case is detected with the compound flag -$$\texttt{1 - not\_special\_len * stack\_inv\_aux,}$$ -where $$\texttt{not\_special\_len = current\_row - special\_len}$$ - - -and \texttt{stack\_inv\_aux} is constrained to be the modular inverse of \texttt{not\_special\_ len} if it's non-zero, or 0 otherwise. The flag is 1 -if \texttt{stack\_len} is equal to \texttt{special\_len}, and 0 otherwise. - -This logic can be found in code in the \texttt{eval\_packed\_one} function of \href{https://github.com/0xPolygonZero/plonky2/blob/main/evm/src/cpu/stack.rs}{stack.rs}. -The function multiplies all of the stack constraints with the degree 1 filter associated with the current instruction. - -\paragraph*{Operation flag merging:} - -To reduce the total number of columns, many operation flags are merged together (e.g. \texttt{DUP} and \texttt{SWAP}) and are distinguished with the binary decomposition of their opcodes. -The filter for a merged operation is now of degree 2: for example, \texttt{is\_swap = dup\_swap * opcode\_bits[4]} since the 4th bit is set to 1 for a \texttt{SWAP} and 0 for a \texttt{DUP}. -If the two instructions have different stack behaviors, this can be a problem: \texttt{eval\_packed\_one}'s constraints are already of degree 3 and it can't support degree 2 filters. - -When this happens, stack constraints are defined manually in the operation's dedicated file (e.g. \texttt{dup\_swap.rs}). Implementation details vary case-by-case and can be found in the files. - -\subsubsection{Stack length checking} - -The CPU must make sure that the stack length never goes below zero and, in user mode, never grows beyond the maximum stack size. When this happens, an honest prover should trigger the -corresponding exception. If a malicious prover doesn't trigger the exception, constraints must fail the proof. - -\paragraph*{Stack underflow:} -There is no explicit constraint checking for stack underflow. An underflow happens when the CPU tries to pop the empty stack, which would perform a memory read at virtual address \texttt{-1}. -Such a read cannot succeed: in Memory, the range-check argument requires the gap between two consecutive addresses to be lower than the length of the Memory trace. Since the prime of the Plonky2 field is 64-bit long, -this would require a Memory trace longer than $2^{32}$. - -\paragraph*{Stack overflow:} -An instruction can only push at most once, meaning that an overflow occurs whenever the stack length is exactly one more than the maximum stack size ($1024+1$) in user mode. -To constrain this, the column \texttt{stack\_len\_bounds\_aux} contains: - -\begin{itemize} - \item[--] the modular inverse of \texttt{stack\_len - 1025} if we're in user mode and \texttt{stack\_len $\neq$ 1025}, - \item[--] 0 if \texttt{stack\_len = 1025} or if we're in kernel mode. -\end{itemize} -Then overflow can be checked with the flag -$$\texttt{(1 - is\_kernel\_mode) - stack\_len * stack\_len\_bounds\_aux}.$$ -The flag is 1 if \texttt{stack\_len = 1025} and we're in user mode, and 0 otherwise. - -Because \texttt{stack\_len\_bounds\_aux} is a shared general column, we only check this constraint after an instruction that can actually trigger an overflow, -i.e. a pushing, non-popping instruction. - -\subsection{Gas handling} - -\subsubsection{Out of gas errors} - -The CPU table has a ``gas'' register that keeps track of the gas used by the transaction so far. - -The crucial invariant in our out-of-gas checking method is that at any point in the program's execution, we have not used more gas than we have available; that is ``gas'' is at most the gas allocation for the transaction (which is stored separately by the kernel). We assume that the gas allocation will never be $2^{32}$ or more, so if ``gas'' does not fit in one limb, then we've run out of gas. - -When a native instruction (one that is not a syscall) is executed, a constraint ensures that the ``gas'' register is increased by the correct amount. This is not automatic for syscalls; the syscall handler itself must calculate and charge the appropriate amount. - -If everything goes smoothly and we have not run out of gas, ``gas'' should be no more than the gas allowance at the point that we STOP, REVERT, stack overflow, or whatever. Indeed, because we assume that the gas overflow handler is invoked \textit{as soon as} we've run out of gas, all these termination methods verify that $\texttt{gas} \leq \texttt{allowance}$, and jump to \texttt{exc\_out\_of\_gas} if this is not the case. This is also true for the out-of-gas handler, which checks that: -\begin{enumerate} - \item we have not yet run out of gas - \item we are about to run out of gas -\end{enumerate} -and ``PANIC'' if either of those statements does not hold. - -When we do run out of gas, however, this event must be handled. Syscalls are responsible for checking that their execution would not cause the transaction to run out of gas. If the syscall detects that it would need to charge more gas than available, it aborts the transaction (or the current code) by jumping to \texttt{fault\_exception}. In fact, \texttt{fault\_exception} is in charge of handling all exceptional halts in the kernel. - -Native instructions do this differently. If the prover notices that execution of the instruction would cause an out-of-gas error, it must jump to the appropriate handler instead of executing the instruction. (The handler contains special code that PANICs if the prover invoked it incorrectly.) - -\subsubsection{Overflow} - -We must be careful to ensure that ``gas'' does not overflow to prevent denial of service attacks. - -Note that a syscall cannot be the instruction that causes an overflow. This is because every syscall is required to verify that its execution does not cause us to exceed the gas limit. Upon entry into a syscall, a constraint verifies that $\texttt{gas} < 2^{32}$. Some syscalls may have to be careful to ensure that the gas check is performed correctly (for example, that overflow modulo $2^{256}$ does not occur). So we can assume that upon entry and exit out of a syscall, $\texttt{gas} < 2^{32}$. - -Similarly, native instructions alone cannot cause wraparound. The most expensive instruction, JUMPI, costs 10 gas. Even if we were to execute $2^{32}$ consecutive JUMPI instructions, the maximum length of a trace, we are nowhere close to consuming $2^{64} - 2^{32} + 1$ (= Goldilocks prime) gas. - -The final scenario we must tackle is an expensive syscall followed by many expensive native instructions. Upon exit from a syscall, $\texttt{gas} < 2^{32}$. Again, even if that syscall is followed by $2^{32}$ native instructions of cost 10, we do not see wraparound modulo Goldilocks. - - -\subsection{Exceptions} -\label{exceptions} - -Sometimes, when executing user code (i.e. contract or transaction code), the EVM halts exceptionally (i.e. outside of a STOP, a RETURN or a REVERT). -When this happens, the CPU table invokes a special instruction with a dedicated operation flag \texttt{exception}. -Exceptions can only happen in user mode; triggering an exception in kernel mode would make the proof unverifiable. -No matter the exception, the handling is the same: - --- The opcode which would trigger the exception is not executed. The operation flag set is \texttt{exception} instead of the opcode's flag. - --- We push a value to the stack which contains: the current program counter (to retrieve the faulty opcode), and the current value of \texttt{gas\_used}. -The program counter is then set to the corresponding exception handler in the kernel (e.g. \texttt{exc\_out\_of\_gas}). - --- The exception handler verifies that the given exception would indeed be triggered by the faulty opcode. If this is not the case (if the exception has already happened or if it doesn't happen after executing -the faulty opcode), then the kernel panics: there was an issue during witness generation. - --- The kernel consumes the remaining gas and returns from the current context with \texttt{success} set to 0 to indicate an execution failure. - -Here is the list of the possible exceptions: - -\begin{enumerate}[align=left] - \item[\textbf{Out of gas:}] Raised when a native instruction (i.e. not a syscall) in user mode pushes the amount of gas used over the current gas limit. -When this happens, the EVM jumps to \texttt{exc\_out\_of\_gas}. The kernel then checks that the consumed gas is currently below the gas limit, -and that adding the gas cost of the faulty instruction pushes it over it. -If the exception is not raised, the prover will panic when returning from the execution: the remaining gas is checked to be positive after STOP, RETURN or REVERT. - \item[\textbf{Invalid opcode:}] Raised when the read opcode is invalid. It means either that it doesn't exist, or that it's a privileged instruction and -thus not available in user mode. When this happens, the EVM jumps to \texttt{exc\_invalid\_opcode}. The kernel then checks that the given opcode is indeed invalid. -If the exception is not raised, decoding constraints ensure no operation flag is set to 1, which would make it a padding row. Halting constraints would then make the proof -unverifiable. - \item[\textbf{Stack underflow:}] Raised when an instruction which pops from the stack is called when the stack doesn't have enough elements. -When this happens, the EVM jumps to \texttt{exc\_stack\_overflow}. The kernel then checks that the current stack length is smaller than the minimum -stack length required by the faulty opcode. -If the exception is not raised, the popping memory operation's address offset would underflow, and the Memory range check would require the Memory trace to be too -large ($>2^{32}$). - \item[\textbf{Invalid JUMP destination:}] Raised when the program counter jumps to an invalid location (i.e. not a JUMPDEST). When this happens, the EVM jumps to -\texttt{exc\_invalid\_jump\_destination}. The kernel then checks that the opcode is a JUMP, and that the destination is not a JUMPDEST by checking the -JUMPDEST segment. -If the exception is not raised, jumping constraints will fail the proof. - \item[\textbf{Invalid JUMPI destination:}] Same as the above, for JUMPI. - \item[\textbf{Stack overflow:}] Raised when a pushing instruction in user mode pushes the stack over 1024. When this happens, the EVM jumps -to \texttt{exc\_stack\_overflow}. The kernel then checks that the current stack length is exactly equal to 1024 (since an instruction can only -push once at most), and that the faulty instruction is pushing. -If the exception is not raised, stack constraints ensure that a stack length of 1025 in user mode will fail the proof. -\end{enumerate} diff --git a/evm/spec/framework.tex b/evm/spec/framework.tex deleted file mode 100644 index c20e46db67..0000000000 --- a/evm/spec/framework.tex +++ /dev/null @@ -1,159 +0,0 @@ -\section{STARK framework} -\label{framework} - - -\subsection{Cost model} - -Our zkEVM is designed for efficient verification by STARKs \cite{stark}, particularly by an AIR with degree 3 constraints.

We need to check that the shared values are identical in all the STARKs that require them. This is where cross-table lookups (CTLs) come in handy. - -Suppose STARK $S_1$ requires an operation -- say $Op$ -- that is carried out by another STARK $S_2$. Then $S_1$ writes the input and output of $Op$ in its own table, and provides the inputs to $S_2$. $S_2$ also writes the inputs and outputs in its rows, and the table's constraints check that $Op$ is carried out correctly. We then need to ensure that the inputs and outputs are the same in $S_1$ and $S_2$. - -In other words, we need to ensure that the rows -- reduced to the input and output columns -- of $S_1$ calling $Op$ are permutations of the rows of $S_2$ that carry out $Op$. Our CTL protocol is based on logUp and is similar to our range-checks. - -To prove this, the first step is to only select the rows of interest in $S_1$ and $S_2$, and filter out the rest. Let $f^1$ be the filter for $S_1$ and $f^2$ the filter for $S_2$. $f^1$ and $f^2$ are constrained to be in $\{0, 1\}$. $f^1 = 1$ (resp. $f^2 = 1$) whenever the row at hand carries out $Op$ in $S_1$ (resp. in $S_2$), and 0 otherwise. Let also $(\alpha, \beta)$ be two random challenges. - -The idea is to create subtables $S_1'$ and $S_2'$ of $S_1$ and $S_2$ respectively, such that $f^1 = 1$ and $f^2 = 1$ for all their rows. The columns in the subtables are limited to the ones whose values must be identical (the inputs and outputs of $Op$ in our example). - -Note that for design and constraint reasons, filters are limited to (at most) degree 2 combinations of columns. - -Let $\{c^{1, i}\}_{i=1}^m$ be the columns in $S_1'$ an $\{c^{2,i}\}_{i=1}^m$ be the columns in $S_2'$. - -The prover defines a ``running sum'' $Z$ for $S_1'$ such that: -\begin{gather*} - Z^{S_1}_{n-1} = \frac{1}{\sum_{j=0}^{m-1} \alpha^j \cdot c^{1, j}_{n-1} + \beta} \\ - Z^{S_1}_{i+1} = Z^{S_1}_i + f^1_i \cdot \frac{1}{\sum_{j=0}^{m-1} \alpha^j \cdot c^{1, j}_i + \beta} -\end{gather*} -The second equation ``selects'' the terms of interest thanks to $f^1$ and filters out the rest. - -Similarly, the prover constructs a running sum $Z^{S_2}$for $S_2$.

To prevent a malicious prover from cheating, it is crucial to range-check those limbs. -\subsubsection{What to range-check?} -One can note that every element that ever appears on the stack has been pushed. Therefore, enforcing a range-check on pushed elements is enough to range-check all elements on the stack. Similarly, all elements in memory must have been written prior, and therefore it is enough to range-check memory writes. However, range-checking the PUSH and MSTORE opcodes is not sufficient. -\begin{enumerate} - \item Pushes and memory writes for ``MSTORE\_32BYTES'' are range-checked in ``BytePackingStark''. - \item Syscalls, exceptions and prover inputs are range-checked in ``ArithmeticStark''. - \item The inputs and outputs of binary and ternary arithmetic operations are range-checked in ``ArithmeticStark''. - \item The inputs' bits of logic operations are checked to be either 1 or 0 in ``LogicStark''. Since ``LogicStark'' only deals with bitwise operations, this is enough to have range-checked outputs as well. - \item The inputs of Keccak operations are range-checked in ``KeccakStark''. The output digest is written as bytes in ``KeccakStark''. Those bytes are used to reconstruct the associated 32-bit limbs checked against the limbs in ``CpuStark''. This implicitly ensures that the output is range-checked. -\end{enumerate} -Note that some operations do not require a range-check: -\begin{enumerate} - \item ``MSTORE\_GENERAL'' read the value to write from the stack. Thus, the written value was already range-checked by a previous push. - \item ``EQ'' reads two -- already range-checked -- elements on the stack, and checks they are equal. The output is either 0 or 1, and does therefore not need to be checked. - \item ``NOT'' reads one -- already range-checked -- element. The result is constrained to be equal to $\texttt{0xFFFFFFFF} - \texttt{input}$, which implicitly enforces the range check. - \item ``PC'': the program counter cannot be greater than $2^{32}$ in user mode. Indeed, the user code cannot be longer than $2^{32}$, and jumps are constrained to be JUMPDESTs. Moreover, in kernel mode, every jump is towards a location within the kernel, and the kernel code is smaller than $2^{32}$. These two points implicitly enforce $PC$'s range check. - \item ``GET\_CONTEXT'', ``DUP'' and ``SWAP'' all read and push values that were already written in memory. The pushed values were therefore already range-checked. -\end{enumerate} -Range-checks are performed on the range $[0, 2^{16} - 1]$, to limit the trace length. - -\subsubsection{Lookup Argument} -To enforce the range-checks, we leverage \href{https://eprint.iacr.org/2022/1530.pdf}{logUp}, a lookup argument by Ulrich Häbock. Given a looking table $s = (s_1, ..., s_n)$ and a looked table $t = (t_1, ..., t_m)$, the goal is to prove that -$$\forall 1 \leq i \leq n, \exists 1 \leq j \leq r \texttt{ such that } s_i = t_j$$ -In our case, $t = (0, .., 2^{16} - 1)$ and $s$ is composed of all the columns in each STARK that must be range-checked. - -The logUp paper explains that proving the previous assertion is actually equivalent to proving that there exists a sequence $l$ such that: -$$ \sum_{i=1}^n \frac{1}{X - s_i} = \sum_{j=1}^r \frac{l_j}{X-t_j}$$ - -The values of $s$ can be stored in $c$ different columns of length $n$ each. In that case, the equality becomes: -$$\sum_{k=1}^c \sum_{i=1}^n \frac{1}{X - s_i^k} = \sum_{j=1}^r \frac{l_j}{X-t_j}$$ - -The `multiplicity' $m_i$ of value $t_i$ is defined as the number of times $t_i$ appears in $s$. In other words: -$$m_i = |s_j \in s; s_j = t_i|$$ - -Multiplicities provide a valid sequence of values in the previously stated equation. Thus, if we store the multiplicities, and are provided with a challenge $\alpha$, we can prove the lookup argument by ensuring: -$$\sum_{k=1}^c \sum_{i=1}^n \frac{1}{\alpha - s_i^k} = \sum_{j=1}^r \frac{m_j}{\alpha-t_j}$$ -However, the equation is too high degree. To circumvent this issue, Häbock suggests providing helper columns $h_i$ and $d$ such that at a given row $i$: -\begin{gather*} - h_i^k = \frac{1}{\alpha + s_i^k } \forall 1 \leq k \leq c \\ - d_i = \frac{1}{\alpha + t_i} -\end{gather*} - -The $h$ helper columns can be batched together to save columns. We can batch at most $\texttt{constraint\_degree} - 1$ helper functions together. In our case, we batch them 2 by 2. At row $i$, we now have: -\begin{align*} - h_i^k = \frac{1}{\alpha + s_i^{2k}} + \frac{1}{\alpha + s_i^{2k+1}} \forall 1 \leq k \leq c/2 \\ -\end{align*} -If $c$ is odd, then we have one extra helper column: -$$h_i^{c/2+1} = \frac{1}{\alpha + s_i^{c}}$$ - -For clarity, we will assume that $c$ is even in what follows. - -Let $g$ be a generator of a subgroup of order $n$. We extrapolate $h, m$ and $d$ to get polynomials such that, for $f \in \{h^k, m, g\}$: $f(g^i) = f_i$. -We can define the following polynomial: -$$ Z(x) := \sum_{i=1}^n \big[\sum_{k=1}^{c/2} h^k(x) - m(x) * d(x)\big]$$ - - -\subsubsection{Constraints} -With these definitions and a challenge $\alpha$, we can finally check that the assertion holds with the following constraints: -\begin{gather*} - Z(1) = 0 \\ - Z(g \alpha) = Z(\alpha) + \sum_{k=1}^{c/2} h^k(\alpha) - m(\alpha) d(\alpha) -\end{gather*} -These ensure that -We also need to ensure that $h^k$ is well constructed for all $1 \leq k \leq c/2$: -$$ - h(\alpha)^k \cdot (\alpha + s_{2k}) \cdot (\alpha + s_{2k+1}) = (\alpha + s_{2k}) + (\alpha + s_{2k+1}) -$$ - -Note: if $c$ is odd, we have one unbatched helper column $h^{c/2+1}$ for which we need a last constraint: -$$ - h(\alpha)^{c/2+1} \cdot (\alpha + s_{c}) = 1 -$$ - -Finally, the verifier needs to ensure that the table $t$ was also correctly computed. In each STARK, $t$ is computed starting from 0 and adding at most 1 at each row.

For optimization purposes, we check all arithmetic operations against the cpu table together. To ensure correctness, we also check that the operation's opcode corresponds to its behavior. But range-check is not associated to a unique operation: any operation in the cpu table might require its values to be checked. Thus, the arithmetic table cannot know its opcode in advance: it needs to store the value provided by the cpu table. - -\subsubsection{Auxiliary columns} -The way auxiliary values are leveraged to efficiently check correctness is not trivial, but it is explained in detail in each dedicated file. Overall, five files explain the implementations of the various checks. Refer to: -\begin{enumerate} - \item ``mul.rs'' for details on multiplications. - \item ``addcy.rs'' for details on addition, subtraction, ``lt'' and ``gt''. - \item ``modular.rs'' for details on how modular operations are checked. Note that even though ``div'' and ``mod'' are generated and checked in a separate file, they leverage the logic for modular operations described in ``modular.rs''. - \item ``byte'' for details on how ``byte'' is checked. - \item ``shift.rs'' for details on how shifts are checked. -\end{enumerate} - -\paragraph*{Note on ``lt'' and ``gt'':} For ``lt'' and ``gt'', auxiliary columns hold the difference $d$ between the two inputs $x_1, x_2$. We can then treat them similarly to subtractions by ensuring that $x_1 - x_2 = d$ for ``lt'' and $x_2 - x_1 = d$ for ``gt''. An auxiliary column $cy$ is used for the carry in additions and subtractions. In the comparisons case, it holds the overflow flag. Contrary to subtractions, the output of ``lt'' and ``gt'' operations is not $d$ but $cy$. - -\paragraph*{Note on ``div'':} It might be unclear why ``div'' and ``mod'' are dealt with in the same file. - -Given numerator and denominator $n, d$, we compute, like for other modular operations, the quotient $q$ and remainder $\texttt{rem}$: -$$div(x_1, x_2) = q * x_2 + \texttt{rem}$$. -We then set the associated auxiliary columns to $\texttt{rem}$ and the output to $q$. - -This is why ``div'' is essentially a modulo operation, and can be addressed in almost the same way as ``mod''. The only difference is that in the ``mod'' case, the output is $\texttt{rem}$ and the auxiliary value is $q$. - -\paragraph{Note on shifts:} ``shr'' and ``shl'' are internally constrained as ``div'' and ``mul'' respectively with shifted operands. Indeed, given inputs $s, x$, the output should be $x >> s$ for ``shr'' (resp. $x << s$ for ``shl''). Since shifts are binary operations, we can use the third input columns to store $s_{\texttt{shifted}} = 1 << s$.

Context 0 is the kernel itself, which -handles initialization (input processing, transaction parsing, transaction trie updating...) and termination (receipt creation, final trie checks...) before and after executing the transaction. Subsequent contexts are created when -executing user code (transaction or contract code). In a non-zero user context, syscalls may be executed, which are specific instructions written in the kernel.

Incremented by 1 at every call. - \item \texttt{code\_context}: Indicates in which context the code to execute resides. It's equal to \texttt{context} in user mode, but is always 0 in kernel mode. - \item \texttt{program\_counter}: The address of the instruction to be read and executed. - \item \texttt{stack\_len}: The current length of the stack. - \item \texttt{is\_kernel\_mode}: Boolean indicating whether we are in kernel (i.e. privileged) mode.

During CPU cycles phase, each row executes a single instruction, which sets one and only one operation flag. No flag is set during -padding. The decoding constraints ensure that the flag set corresponds to the opcode being read. -There isn't a 1-to-1 correspondance between instructions and flags. For efficiency, the same flag can be set by different, unrelated instructions (e.g. \texttt{eq\_iszero}, which represents -the \texttt{EQ} and the \texttt{ISZERO} instructions). When there is a need to differentiate them in constraints, we filter them with their respective opcode: since the first bit of \texttt{EQ}'s opcode -(resp. \texttt{ISZERO}'s opcode) is 0 (resp. 1), we can filter a constraint for an EQ instruction with \texttt{eq\_iszero * (1 - opcode\_bits[0])} -(resp. \texttt{eq\_iszero * opcode\_bits[0]}). - -\paragraph*{Memory columns:} The CPU interacts with the EVM memory via its memory channels. At each row, a memory channel can execute a write, a read, or be disabled. A full memory channel is composed of: -\begin{itemize} - \item \texttt{used}: Boolean flag. If it's set to 1, a memory operation is executed in this channel at this row. If it's set to 0, no operation is done but its columns might be reused for other purposes. - \item \texttt{is\_read}: Boolean flag indicating if a memory operation is a read or a write. - \item 3 \texttt{address} columns. A memory address is made of three parts: \texttt{context}, \texttt{segment} and \texttt{virtual}. - \item 8 \texttt{value} columns. EVM words are 256 bits long, and they are broken down in 8 32-bit limbs. -\end{itemize} -The last memory channel is a partial channel: it doesn't have its own \texttt{value} columns and shares them with the first full memory channel. This allows us to save eight columns. - -\paragraph*{General columns:} There are 8 shared general columns.

To prove it, each general column contains the modular inverse of $(\texttt{input0}_i - \texttt{input1}_i)$ -for each limb $i$ (or 0 if the limbs are equal). Then the quantity $\texttt{general}_i * (\texttt{input0}_i - \texttt{input1}_i)$ will be 1 if and only if $\texttt{general}_i$ is -indeed the modular inverse, which is only possible if the difference is non-zero. - \item \texttt{Jumps}: For jumps, we use the first two columns: \texttt{should\_jump} and \texttt{cond\_sum\_pinv}. \texttt{should\_jump} conditions whether the EVM should jump: it's -1 for a JUMP, and $\texttt{condition} \neq 0$ for a JUMPI. To check if the condition is actually non-zero for a JUMPI, \texttt{cond\_sum\_pinv} stores the modular inverse of -\texttt{condition} (or 0 if it's zero). - \item \texttt{Shift}: For shifts, the logic differs depending on whether the displacement is lower than $2^{32}$, i.e. if it fits in a single value limb. -To check if this is not the case, we must check that at least one of the seven high limbs is not zero. The general column \texttt{high\_limb\_sum\_inv} holds the modular inverse -of the sum of the seven high limbs, and is used to check it's non-zero like the previous cases. -Contrary to the logic operations, we do not need to check limbs individually: each limb has been range-checked to 32 bits, meaning that it's not possible for the sum to -overflow and be zero if some of the limbs are non-zero. - \item \texttt{Stack}: \texttt{stack\_inv}, \texttt{stack\_inv\_aux} and \texttt{stack\_inv\_aux\_2} are used by popping-only (resp. pushing-only) instructions to check if the stack is empty after (resp. was empty -before) the instruction. \texttt{stack\_len\_bounds\_ aux} is used to check that the stack doesn't overflow in user mode.

These steps are written as: $$B[y, 2\times x + 3 \times y] := \texttt{rot}(A'[x, y], r[x, y])$$ where $\texttt{rot(a, s)}$ is the bitwise cyclic shift operation, and $r$ is the matrix of rotation offsets. We do not need to store $B$: $B$'s bits are only a permutation of $A'$'s bits. - \item The $\chi$ step updates the state once again, and we store the new values: $$A''[x, y] := B[x, y] \texttt{ xor } (\texttt{not }B[x+1, y] \texttt{ and } B[x+2, y])$$ Because of the way we carry out constraints (as explained below), we do not need to store the individual bits for $A''$: we only need the 32-bit limbs. - \item The final step, $\iota$, consists in updating the first element of the state as follows: $$A'''[0, 0] = A''[0, 0] \texttt{ xor } RC[i]$$ where $$A'''[x, y] = A''[x, y] \forall (x, y) \neq (0, 0)$$ Since only the first element is updated, we only need to store $A'''[0, 0]$ of this updated state.

Let us detail them here. - -First, it is important to highlight the fact that a $\texttt{xor}$ between two elements is of degree 2. Indeed, for $x \texttt{ xor } y$, the constraint is $x + y - 2 \times x \times y$, which is of degree 2. This implies that a $\texttt{xor}$ between 3 elements is of degree 3, which is the maximal constraint degree for our STARKs. - -We can check that $C'[x, z] = C[x, z] \texttt{ xor } C[x - 1, z] \texttt{ xor } C[x + 1, z - 1]$. However, we cannot directly check that $C[x] = \texttt{xor}_{i=0}^4 A[x, i]$, as it would be a degree 5 constraint. Instead, we use $C'$ for this constraint. We see that: -$$\texttt{xor}_{i=0}^4 A'[x, i, z] = C'[x, z]$$ -This implies that the difference $d = \sum_{i=0}^4 A'[x, i, z] - C'[x, z]$ is either 0, 2 or 4. We can therefore enforce the following degree 3 constraint instead: -$$d \times (d - 2) \times (d - 4) = 0$$ - -Additionally, we have to check that $A'$ is well constructed. We know that $A'$ should be such that $A'[x, y, z] = A[x, y, z] \texttt{ xor } C[x, z] \texttt{ xor } C'[x, z]$. Since we do not have the bits of $A$ elements but the bits of $A'$ elements, we check the equivalent degree 3 constraint: -$$A[x, y, z] = A'[x, y, z] \texttt{ xor } C[x, z] \texttt { xor } C'[x, z]$$ - -Finally, the constraints for the remaining elements, $A''$ and $A'''$ are straightforward: $A''$ is a three-element bitwise $\texttt{xor}$ where all bits involved are already storedn and $A'''[0, 0]$ is the output of a simple bitwise $\texttt{xor}$ with a round constant. \ No newline at end of file diff --git a/evm/spec/tables/keccak-sponge.tex b/evm/spec/tables/keccak-sponge.tex deleted file mode 100644 index a712335b8f..0000000000 --- a/evm/spec/tables/keccak-sponge.tex +++ /dev/null @@ -1,66 +0,0 @@ -\subsection{KeccakSponge} -\label{keccak-sponge} - -This table computes the Keccak256 hash, a sponge-based hash built on top of the Keccak-f[1600] permutation.

The generalization to multi-element addresses and values is straightforward. - -Each row of the memory table corresponds to a single memory operation (a read or a write), and contains the following columns: - -\begin{enumerate} - \item $a$, the target address - \item $r$, an ``is read'' flag, which should be 1 for a read or 0 for a write - \item $v$, the value being read or written - \item $\tau$, the timestamp of the operation -\end{enumerate} -The memory table should be ordered by $(a, \tau)$. Note that the correctness of the memory could be checked as follows: -\begin{enumerate} - \item Verify the ordering by checking that $(a_i, \tau_i) \leq (a_{i+1}, \tau_{i+1})$ for each consecutive pair. - \item Enumerate the purportedly-ordered log while tracking the ``current'' value of $v$. - \begin{enumerate} - \item Upon observing an address which doesn't match that of the previous row, if the address is zero-initialized - and if the operation is a read, check that $v = 0$. - \item Upon observing a write, don't constrain $v$. - \item Upon observing a read at timestamp $\tau_i$ which isn't the first operation at this address, check that $v_i = v_{i-1}$. - \end{enumerate} -\end{enumerate} - -The ordering check is slightly involved since we are comparing multiple columns.

Within that address space, there are separate segments for code, main memory, stack memory, calldata, and returndata. Thus each address actually has three compoments: -\begin{enumerate} - \item an execution context, representing a contract call, - \item a segment ID, used to separate code, main memory, and so forth, and so on - \item a virtual address. -\end{enumerate} -The comparisons now involve several columns, which requires some minor adaptations to the technique described above; we will leave these as an exercise to the reader. - -Note that an additional constraint check is required: whenever we change the context or the segment, the virtual address must be range-checked to $2^{32}$. -Without this check, addresses could start at -1 (i.e. $p - 2$) and then increase properly. - -\subsubsection{Timestamps} - -Memory operations are sorted by address $a$ and timestamp $\tau$. For a memory operation in the CPU, we have: -$$\tau = \texttt{NUM\_CHANNELS} \times \texttt{cycle} + \texttt{channel}.$$ -Since a memory channel can only hold at most one memory operation, every CPU memory operation's timestamp is unique. - -Note that it doesn't mean that all memory operations have unique timestamps. There are two exceptions: - -\begin{itemize} - \item Before the CPU cycles, we write some global metadata in memory. These extra operations are done at timestamp $\tau = 0$. - \item Some tables other than CPU can generate memory operations, like KeccakSponge. When this happens, these operations all have the timestamp of the CPU row of the instruction which invoked the table (for KeccakSponge, KECCAK\_GENERAL). -\end{itemize} - -\subsubsection{Memory initialization} - -By default, all memory is zero-initialized. However, to save numerous writes, we allow some specific segments to be initialized with arbitrary values. - -\begin{itemize} - \item The read-only kernel code (in segment 0, context 0) is initialized with its correct values. It's checked by hashing the segment and verifying -that the hash value matches a verifier-provided one. - \item The code segment (segment 0) in other contexts is initialized with externally-provided account code, then checked against the account code hash. -If the code is meant to be executed, there is a soundness concern: if the code is malformed and ends with an incomplete PUSH, then the missing bytes must -be 0 accordingly to the Ethereum specs. To prevent the issue, we manually write 33 zeros (at most 32 bytes for the PUSH argument, and an extra one for -the post-PUSH PC value). - \item The ``TrieData'' segment is initialized with the input tries. The stored tries are hashed and checked against the provided initial hash. Note that the length of the segment and the pointers -- within the ``TrieData'' segment -- for the three tries are provided as prover inputs. The length is then checked against a value computed when hashing the tries. -\end{itemize} diff --git a/evm/spec/zkevm.pdf b/evm/spec/zkevm.pdf deleted file mode 100644 index

Support for the EVM BYTE instruction -//! -//! This crate verifies the EVM BYTE instruction, defined as follows: -//! -//! INPUTS: 256-bit values I and X = \sum_{i=0}^31 X_i B^i, -//! where B = 2^8 and 0 <= X_i < B for all i. -//! -//! OUTPUT: X_{31-I} if 0 <= I < 32, otherwise 0. -//! -//! NB: index I=0 corresponds to byte X_31, i.e. the most significant -//! byte. This is exactly the opposite of anyone would expect; who -//! knows what the EVM designers were thinking. Anyway, if anything -//! below seems confusing, first check to ensure you're counting from -//! the wrong end of X, as the spec requires. -//! -//! Wlog consider 0 <= I < 32, so I has five bits b0,...,b4. We are -//! given X as an array of 16-bit limbs; write X := \sum_{i=0}^15 Y_i -//! 2^{16i} where 0 <= Y_i < 2^16. -//! -//! The technique (hat tip to Jacqui for the idea) is to store a tree -//! of limbs of X that are selected according to the bits in I. The -//! main observation is that each bit `bi` halves the number of -//! candidate bytes that we might return: If b4 is 0, then I < 16 and -//! the possible bytes are in the top half of X: Y_8,..,Y_15 -//! (corresponding to bytes X_16,..,X_31), and if b4 is 1 then I >= 16 -//! and the possible bytes are the bottom half of X: Y_0,..,Y_7 -//! (corresponding to bytes X_0,..,X_15). -//! -//! Let Z_0,..,Z_7 be the bytes selected in the first step. Then, in -//! the next step, if b3 is 0, we select Z_4,..,Z_7 and if it's 1 we -//! select Z_0,..,Z_3. Together, b4 and b3 divide the bytes of X into -//! 4 equal-sized chunks of 4 limbs, and the byte we're after will be -//! among the limbs 4 selected limbs. -//! -//! Repeating for b2 and b1, we reduce to a single 16-bit limb -//! L=x+y*256; the desired byte will be x if b0 is 1 and y if b0 -//! is 0. -//! -//! -*- -//! -//! To prove that the bytes x and y are in the range [0, 2^8) (rather -//! than [0, 2^16), which is all the range-checker guarantees) we do -//! the following (hat tip to Jacqui for this trick too): Instead of -//! storing x and y, we store w = 256 * x and y. Then, to verify that -//! x, y < 256 and the last limb L = x + y * 256, we check that -//! L = w / 256 + y * 256. -//! -//! The proof of why verifying that L = w / 256 + y * 256 -//! suffices is as follows: -//! -//! 1. The given L, w and y are range-checked to be less than 2^16. -//! 2. y * 256 ∈ {0, 256, 512, ..., 2^24 - 512, 2^24 - 256} -//! 3. w / 256 = L - y * 256 ∈ {-2^24 + 256, -2^24 + 257, ..., 2^16 - 2, 2^16 - 1} -//! 4. By inspection, for w < 2^16, if w / 256 < 2^16 or -//! w / 256 >= P - 2^24 + 256 (i.e. if w / 256 falls in the range -//! of point 3 above), then w = 256 * m for some 0 <= m < 256. -//! 5. Hence w / 256 ∈ {0, 1, ..., 255} -//! 6. Hence y * 256 = L - w / 256 ∈ {-255, -254, ..., 2^16 - 1} -//! 7. Taking the intersection of ranges in 2. and 6. we see that -//! y * 256 ∈ {0, 256, 512, ..., 2^16 - 256} -//! 8.

Support for the EVM modular instructions ADDMOD, SUBMOD, MULMOD and MOD, -//! as well as DIV and FP254 related modular instructions. -//! -//! This crate verifies an EVM modular instruction, which takes three -//! 256-bit inputs A, B and M, and produces a 256-bit output C satisfying -//! -//! C = operation(A, B) (mod M). -//! -//! where operation can be addition, multiplication, or just return -//! the first argument (for MOD). Inputs A, B and M, and output C, -//! are given as arrays of 16-bit limbs. For example, if the limbs of -//! A are a[0]...a[15], then -//! -//! A = \sum_{i=0}^15 a[i] β^i, -//! -//! where β = 2^16 = 2^LIMB_BITS. To verify that A, B, M and C satisfy -//! the equation we proceed as follows. Define -//! -//! a(x) = \sum_{i=0}^15 a[i] x^i -//! -//! (so A = a(β)) and similarly for b(x), m(x) and c(x). Then -//! operation(A,B) = C (mod M) if and only if there exists q such that -//! the polynomial -//! -//! operation(a(x), b(x)) - c(x) - m(x) * q(x) -//! -//! is zero when evaluated at x = β, i.e. it is divisible by (x - β); -//! equivalently, there exists a polynomial s such that -//! -//! operation(a(x), b(x)) - c(x) - m(x) * q(x) - (x - β) * s(x) == 0 -//! -//! if and only if operation(A,B) = C (mod M). In the code below, this -//! "constraint polynomial" is constructed in the variable -//! `constr_poly`. It must be identically zero for the modular -//! operation to be verified, or, equivalently, each of its -//! coefficients must be zero. The variable names of the constituent -//! polynomials are (writing N for N_LIMBS=16): -//! -//! a(x) = \sum_{i=0}^{N-1} input0[i] * x^i -//! b(x) = \sum_{i=0}^{N-1} input1[i] * x^i -//! c(x) = \sum_{i=0}^{N-1} output[i] * x^i -//! m(x) = \sum_{i=0}^{N-1} modulus[i] * x^i -//! q(x) = \sum_{i=0}^{2N-1} quot[i] * x^i -//! s(x) = \sum_i^{2N-2} aux[i] * x^i -//! -//! Because A, B, M and C are 256-bit numbers, the degrees of a, b, m -//! and c are (at most) N-1 = 15. If m = 1, then Q would be A*B which -//! can be up to 2^512 - ε, so deg(q) can be up to 2*N-1 = 31. Note -//! that, although for arbitrary m and q we might have deg(m*q) = 3*N-2, -//! because the magnitude of M*Q must match that of operation(A,B), we -//! always have deg(m*q) <= 2*N-1. Finally, in order for all the degrees -//! to match, we have deg(s) <= 2*N-2 = 30. -//! -//! -*- -//! -//! To verify that the output is reduced, that is, output < modulus, -//! the prover supplies the value `out_aux_red` which must satisfy -//! -//! output - modulus = out_aux_red + 2^256 -//! -//! and these values are passed to the "less than" operation. -//! -//! -*- -//! -//! The EVM defines division by zero as zero. We handle this as -//! follows: -//! -//! The prover supplies a binary value `mod_is_zero` which is one if -//! the modulus is zero and zero otherwise. This is verified, then -//! added to the modulus (this can't overflow, as modulus[0] was -//! range-checked and mod_is_zero is 0 or 1). The rest of the -//! calculation proceeds as if modulus was actually 1; this correctly -//! verifies that the output is zero, as required by the standard. -//! To summarise: -//! -//! - mod_is_zero is 0 or 1 -//! - if mod_is_zero is 1, then -//! - given modulus is 0 -//! - updated modulus is 1, which forces the correct output of 0 -//! - if mod_is_zero is 0, then -//! - given modulus can be 0 or non-zero -//! - updated modulus is same as given -//! - if modulus is non-zero, correct output is obtained -//! - if modulus is 0, then the test output < modulus, checking that -//! the output is reduced, will fail, because output is non-negative. -//! -//! In the case of DIV, we do something similar, except that we "replace" -//! the modulus with "2^256" to force the quotient to be zero. -//! -//! -*- -//! -//! NB: The implementation uses 9 * N_LIMBS = 144 columns because of -//! the requirements of the general purpose MULMOD; since ADDMOD, -//! SUBMOD, MOD and DIV are currently implemented in terms of the -//! general modular code, they also take 144 columns. Possible -//! improvements: -//! -//! - We could reduce the number of columns to 112 for ADDMOD, SUBMOD, -//! etc. if they were implemented separately, so they don't pay the -//! full cost of the general MULMOD. -//! -//! - All these operations could have alternative forms where the -//! output was not guaranteed to be reduced, which is often sufficient -//! in practice, and which would save a further 16 columns. -//! -//! - If the modulus is known in advance (such as for elliptic curve -//! arithmetic), specialised handling of MULMOD in that case would -//! only require 96 columns, or 80 if the output doesn't need to be -//! reduced. - -use core::ops::Range; - -use ethereum_types::U256; -use num::bigint::Sign; -use num::{BigInt, One, Zero}; -use plonky2::field::extension::Extendable; -use plonky2::field::packed::PackedField; -use plonky2::field::types::{Field, PrimeField64}; -use plonky2::hash::hash_types::RichField; -use plonky2::iop::ext_target::ExtensionTarget; -use plonky2::plonk::circuit_builder::CircuitBuilder; -use starky::constraint_consumer::{ConstraintConsumer, RecursiveConstraintConsumer}; -use static_assertions::const_assert; - -use super::columns; -use crate::arithmetic::addcy::{eval_ext_circuit_addcy, eval_packed_generic_addcy}; -use crate::arithmetic::columns::*; -use crate::arithmetic::utils::*; -use crate::extension_tower::BN_BASE; - -const fn bn254_modulus_limbs() -> [u16; N_LIMBS] { - const_assert!(N_LIMBS == 16); // Assumed below - let mut limbs = [0u16; N_LIMBS]; - let mut i = 0; - while i < N_LIMBS / 4 { - let x = BN_BASE.0[i]; - limbs[4 * i] = x as u16; - limbs[4 * i + 1] = (x >> 16) as u16; - limbs[4 * i + 2] = (x >> 32) as u16; - limbs[4 * i + 3] = (x >> 48) as u16; - i += 1; - } - limbs -} - -/// Convert the base-2^16 representation of a number into a BigInt. -/// -/// Given `N` signed (16 + ε)-bit values in `limbs`, return the BigInt -/// -/// \sum_{i=0}^{N-1} limbs[i] * β^i. -/// -/// This is basically "evaluate the given polynomial at β".

Support for the EVM MUL instruction. -//! -//! This crate verifies an EVM MUL instruction, which takes two -//! 256-bit inputs A and B, and produces a 256-bit output C satisfying -//! -//! C = A*B (mod 2^256), -//! -//! i.e. C is the lower half of the usual long multiplication -//! A*B. Inputs A and B, and output C, are given as arrays of 16-bit -//! limbs.

It must be identically zero for the -//! multiplication operation to be verified, or, equivalently, each of -//! its coefficients must be zero.

To this end, the plonky2 zk-EVM is tailored for an AIR-based STARK system satisfying degree 3 constraints, -//! with support for recursive aggregation leveraging plonky2 circuits with FRI-based plonkish arithmetization. -//! These circuits require a one-time, offline preprocessing phase. -//! See the [`fixed_recursive_verifier`] module for more details on how this works. -//!

Transactions need to be processed into an Intermediary Representation (IR) format for the prover -//! to be able to generate proofs of valid state transition. This involves passing the encoded transaction, -//! the header of the block in which it was included, some information on the state prior execution -//! of this transaction, etc. -//! This intermediary representation is called [`GenerationInputs`]. -//! -//! -//! # Generating succinct proofs -//! -//! ## Transaction proofs -//! -//! To generate a proof for a transaction, given its [`GenerationInputs`] and an [`AllRecursiveCircuits`] -//! prover state, one can simply call the [prove_root](AllRecursiveCircuits::prove_root) method. -//! -//! ```ignore -//! let mut timing = TimingTree::new("prove", log::Level::Debug); -//! let kill_signal = None; // Useful only with distributed proving to kill hanging jobs. -//! let (proof, public_values) = -//! prover_state.prove_root(all_stark, config, inputs, &mut timing, kill_signal); -//! ``` -//! -//! This outputs a transaction proof and its associated public values. These are necessary during the -//! aggregation levels (see below). If one were to miss the public values, they are also retrievable directly -//! from the proof's encoded public inputs, as such: -//! -//! ```ignore -//! let public_values = PublicValues::from_public_inputs(&proof.public_inputs); -//! ``` -//! -//! ## Aggregation proofs -//! -//! Because the plonky2 zkEVM generates proofs on a transaction basis, we then need to aggregate them for succinct -//! verification. This is done in a binary tree fashion, where each inner node proof verifies two children proofs, -//! through the [prove_aggregation](AllRecursiveCircuits::prove_aggregation) method. -//! Note that the tree does *not* need to be complete, as this aggregation process can take as inputs both regular -//! transaction proofs and aggregation proofs. We only need to specify for each child if it is an aggregation proof -//! or a regular one. -//! -//! ```ignore -//! let (proof_1, pv_1) = -//! prover_state.prove_root(all_stark, config, inputs_1, &mut timing, None); -//! let (proof_2, pv_2) = -//! prover_state.prove_root(all_stark, config, inputs_2, &mut timing, None); -//! let (proof_3, pv_3) = -//! prover_state.prove_root(all_stark, config, inputs_3, &mut timing, None); -//! -//! // Now aggregate proofs for txn 1 and 2. -//! let (agg_proof_1_2, pv_1_2) = -//! prover_state.prove_aggregation(false, proof_1, pv_1, false, proof_2, pv_2); -//! -//! // Now aggregate the newly generated aggregation proof with the last regular txn proof. -//! let (agg_proof_1_3, pv_1_3) = -//! prover_state.prove_aggregation(true, agg_proof_1_2, pv_1_2, false, proof_3, pv_3); -//! ``` -//! -//! **Note**: The proofs provided to the [prove_aggregation](AllRecursiveCircuits::prove_aggregation) method *MUST* have contiguous states. -//! Trying to combine `proof_1` and `proof_3` from the example above would fail. -//! -//! ## Block proofs -//! -//! Once all transactions of a block have been proven and we are left with a single aggregation proof and its public values, -//! we can then wrap it into a final block proof, attesting validity of the entire block. -//! This [prove_block](AllRecursiveCircuits::prove_block) method accepts an optional previous block proof as argument, -//! which will then try combining the previously proven block with the current one, generating a validity proof for both. -//! Applying this process from genesis would yield a single proof attesting correctness of the entire chain. -//! -//! ```ignore -//! let previous_block_proof = { ... }; -//! let (block_proof, block_public_values) = -//! prover_state.prove_block(Some(&previous_block_proof), &agg_proof, agg_pv)?; -//! ``` -//! -//! ### Checkpoint heights -//! -//! The process of always providing a previous block proof when generating a proof for the current block may yield some -//! undesirable issues. For this reason, the plonky2 zk-EVM supports checkpoint heights. At given block heights, -//! the prover does not have to pass a previous block proof. This would in practice correspond to block heights at which -//! a proof has been generated and sent to L1 for settlement. -//! -//! The only requirement when generating a block proof without passing a previous one as argument is to have the -//! `checkpoint_state_trie_root` metadata in the `PublicValues` of the final aggregation proof be matching the state -//! trie before applying all the included transactions. If this condition is not met, the prover will fail to generate -//! a valid proof. -//! -//! -//! ```ignore -//! let (block_proof, block_public_values) = -//! prover_state.prove_block(None, &agg_proof, agg_pv)?; -//! ``` -//! -//! # Prover state serialization -//! -//! Because the recursive circuits only need to be generated once, they can be saved to disk once the preprocessing phase -//! completed successfully, and deserialized on-demand. -//! The plonky2 zk-EVM provides serialization methods to convert the entire prover state to a vector of bytes, and vice-versa. -//! This requires the use of custom serializers for gates and generators for proper recursive circuit encoding. This crate provides -//! default serializers supporting all custom gates and associated generators defined within the [`plonky2`] crate. -//! -//! ```ignore -//! let prover_state = AllRecursiveCircuits::::new(...); -//! -//! // Default serializers -//! let gate_serializer = DefaultGateSerializer; -//! let generator_serializer = DefaultGeneratorSerializer:: { -//! _phantom: PhantomData::, -//! }; -//! -//! // Serialize the prover state to a sequence of bytes -//! let bytes = prover_state.to_bytes(false, &gate_serializer, &generator_serializer).unwrap(); -//! -//! // Deserialize the bytes into a prover state -//! let recovered_prover_state = AllRecursiveCircuits::::from_bytes( -//! &all_circuits_bytes, -//! false, -//! &gate_serializer, -//! &generator_serializer, -//! ).unwrap(); -//! -//! assert_eq!(prover_state, recovered_prover_state); -//! ``` -//! -//!
